You will be using the observations given in the scenarios i - vi below to determine which of the following is true for G (a - c), which of the following is true for S (d - f) and which of the following is true for H (g - i).

a. The sign of G is positive.
b. The sign of G is negative.
c. Cannot determine the sign of G from the information given.
d. The sign of S is positive.
e. The sign of S is negative.
f. Cannot determine the sign of S from the information given.
g. The sign of H is positive.
h. The sign of H is negative.
i. Cannot determine the sign of H from the information given.

i. A spontaneous reaction is taking place in a flask. When you touch the flask, it feels cold and gets colder as the reaction progresses.
Input format: in alphabetical order something like c, d,i
ii. A spontaneous reaction is taking place in a flask as evidenced by the formation of gas bubbles. When you touch the flask, it feels hot and gets hotter as the reaction progresses.
Input format: in alphabetical order something like c, d,i
iii. A spontaneous reaction is taking place in a flask. When you touch the flask, it feels hot and gets hotter as the reaction progresses.
Input format: in alphabetical order something like c, d,i
iv. A spontaneous reaction is taking place in a flask. You notice the formation of gas bubbles intensifies as the reaction progresses.
Input format: in alphabetical order something like c, d,i
v. A solid in a closed flask begins to melt. (You can consider this a phase change.)
Input format: in alphabetical order something like c, d,i
vi. A liquid begins to appear on the inside of a closed flask. At first glance before the liquid began to appear, you might have thought the flask was empty. (You can consider this a phase change.)
Input format: in alphabetical order something like c, d,i
